What was meant to be a two week summer vacation in the mountains of Pennsylvania became anything from ordinary for Greg and Katie. On their first visit to an abandoned house, the two stumbled upon a mysterious chest that held more than they expected. By the time the children realized what they had discovered they were already in the world of Autou and soon caught in a powerful struggle between good and evil. With their new friend Robyn, Greg and Katie were enlisted to help save two people from their own world, as well as free countless inhabitants from the fearful Ophis whose goal was to return all of Autou to darkness and slavery. The three children had a difficult journey ahead which involved a magic ring, new creatures, and an ancient prophecy all the while trying to be home in time for dinner.
